This is the fifth volume in the series of books on the Southeast Asian water environment. The most important articles presented at the Eighth, Ninth and Tenth International Symposiums on Southeast Asian Water Environment have been selected for this book. It covers monitoring, treatment, and management issues related with environmental water, water supply, and wastewater. As the emerging issues, pollution with micropollutants and effects of climate change on water environment are also included. This publication is the result of building an academic network among researchers of related fields from different regions to exchange information. This book is an invaluable source of information for researchers, policy makers, NGOs, NPOs, and those who are concerned with achieving global sustainability within the water environment in developing regions.

The Southeast Asian environment has been degraded by the release of industrial and domestic wastes, agricultural and aquacultural chemicals, and pollutants from automobiles. It suffers from water-related disasters, such as tsunamis, floods, typhoons, etc. In order to deal with these issues an integrated approach from the inhabitants, governments and researchers is essential. The environmental threats arising from the increasing population, overuse of natural resources, industrialization, urbanization, and natural disasters present ever increasing challenges to pursuing sustainable development of the region. Many developed countries such as Japan have experiences of dealing with severe environmental pollution and this publication is the result of building an academic network among researchers of related fields from different regions to exchange information. The most important articles presented at the Fourth and Fifth International Symposiums on Southeast Asian Water Environment have been selected for this book. This book will be an invaluable source of information for all those concerned with achieving global sustainability within the water environment in developing regions, including researchers, policy makers, NGOs and NPOs.

This book presents the selected papers presented at the 5th International Symposium on Water Pollution and Treatment (ISWPT 2022), held during October 28–29, 2022, in Bangkok, Thailand. It consists of themes pertaining to water management, policy and governance, and water governance and provides readers with comprehensive information on the principles of sustainable water resources management, as well as recent advances, directions for future research, and policy development for sustainable water resources management. This book is of interest to scientists, engineers, government officials, and water resource managers.

This is the fourth volume in the series of books on the Southeast Asian water environment. The most important articles presented at the Sixth and Seventh International Symposiums on Southeast Asian Water Environment have been selected for this book. It covers water environment management, biological and physico-chemical processes in water and wastewater treatment, monitoring approaches, and water related health issues. This publication is the result of building an academic network among researchers of related fields from different regions to exchange information. This book will be an invaluable source of information for researchers, policy makers, NGOs, NPOs, and those who are concerned with achieving global sustainability within the water environment in developing regions.

In view of the current global scenario, which highlighted the importance of sustainable development and sustaining natural resources, the theme selected for the 2nd Regional ECOMOD 2007 Conference was indeed appropriate. This conference has generated overwhelming interest and I am sure the participants have focussed diligently on the serious issues concerning important environmental issues and steps needed to be taken towards a sustainable development and management of our natural resources and environment. As governments in the Asian region introduce new initiatives and development policies to rejuvenate and protect their environment and natural resources, it is imperative that universities and research institutions play a fundamental role in ensuring that the objectives of these policies are realized. Such institutions can complement government proposals by embarking on research that is relevant and valuable to the needs of respective nations and pursuing extensive research so that the outcome and technology generated can be transferred effectively to the end users. This concerted effort by all the researchers from different fields to improve and manage our natural resources should be lauded. I strongly believe that this conference is an extraordinary testimony to our capacity building at regional and local levels. I believe USM has something interesting to share with all of you in this area. Finally, on behalf of the Organizing Committee, I hope readers will find this book of proceedings useful, informative and stimulating.

This book comprises selected proceedings of the 5th International Conference on Water Resources 2021 (ICWR2021) focusing on innovations and preparations to face the water-related challenges. Focus is given in the area of quantitative and qualitative water resource analyses comprising of forecasting, modelling and water governance. The contents will be useful to researchers, educators, practitioners and policy-makers alike.
